Audio Cut

Hey Indie Hackers 👋
I’m the maker of AudioCut, a lightweight online tool to trim and cut audio files directly in the browser.
This is the story behind why I built it, how I launched it, and what I learned along the way.
The Problem: Audio Editing Is Overkill for Simple Tasks
I frequently needed to trim audio clips:
Cutting podcast highlights
Making ringtones from music
Extracting snippets for TikTok / YouTube Shorts
But every time, I had to open heavy tools like Audacity, Premiere, or mobile apps full of ads and watermarks.
For something as simple as cutting a few seconds of audio, the friction was ridiculous.
So I asked myself:
Why isn’t there a fast, no-login, no-install audio cutter that just works?
The Idea: Upload → Trim → Download
I wanted AudioCut to be:
Instant – no signup, no ads, no waiting
Private – files deleted automatically
Lossless – no re-encoding quality loss
Cross-platform – works on desktop and mobile
The UX goal was simple:
Upload → Trim → Download. Nothing else.
How It Works (Tech Stack)
FFmpeg for audio processing
WebAssembly for fast in-browser execution
Minimal backend for file handling and cleanup
Clean UI with zero distractions
I focused more on speed and reliability than fancy features.
Launch Strategy
I launched AudioCut with a very simple distribution plan:
SEO pages targeting keywords like audio cutter online, trim mp3, cut audio
Product Hunt launch (with founder comment + demo GIF)
Sharing on Indie Hackers and X
No paid ads. Just organic search + community.
Early Feedback & Learnings
1. People love “No Signup”
This is the #1 feature users mention.
2. Speed > Features
Most users just want fast trimming, not DAW-level editing.
3. SEO Works for Simple Tools
Long-tail keywords like:
cut mp3 online
trim wav file
ringtone maker
brought surprising organic traffic.
What’s Next for AudioCut
Planned features:
Batch audio trimming
Merge multiple audio files
Fade in/out effects
Cloud storage integrations
API for developers
Still keeping it lightweight and free.
